“…Metal biosorption by microorganisms is a complex process that depends on the chemistry of the metal ions, cell wall composition of microorganisms, cell physiology, and physicochemical factors such as pH, temperature, time, ionic strength and metal concentration (Hassan et al, 2009;Gabr et al, 2008;Tuzen et al, 2008;GodlewskaZylkiewicz, 2006;Mapoletoet al, 2005;Chaisuksant 2003;Goyalet al, 2003;Volesky 2003;Klimmeket al, 2001;Leung et al, 2001). Removal of toxic heavy metal ions from polluted waste waters by bacterial biomass has been studied extensively in the last few decades (Joo et al, 2010, Hassan et al, 2009Tuzen et al, 2008;Akhtar et al, 2007;Kadukova and Vircikova 2005;Chaisuksant, 2003;Leung et al, 2001;Veglio et al, 1997;Akthar and Mohan, 1995;Fourest et al, 1994;Volesky, 2003;1994;.…”
